——抹芽控梢,降低虫口密度。对零星抽发的夏、秋梢嫩芽,及地抹除,从减少潜叶蛾的食源,降低虫口密度,减轻受害。 ——预测预报,掌握危害高峰期,避开高峰期放梢。柑桔潜叶蛾一年发生7～10代,7～9月是危害盛期。潜叶蛾多在清晨羽化,半小时后交配,经1～4天夜间产卵。根据这一规律,掌握其羽化产卵高峰期,并选择这段时间内相应的低温期(各虫期发育缓慢),当卵和低龄幼虫数量由多转少,嫩梢顶部4～5张嫩叶无幼虫危害的,立即抹除受害梢,统一放梢。
- Wipe Bud control tips to reduce insect population density. On the sporadic pumping summer, autumn shoots buds, and to erase, from reducing the food supply of leaf moths, reduce population density, reduce victimization. - Forecasting, grasping the peak of danger, avoiding the peak release. Citrus leaf moth occurs 7 to 10 generations a year, July to September is the damaging period. More leaf moths eclosion in the early morning, half an hour after mating, by 1 to 4 days to lay eggs at night. According to this law, to grasp the peak of its fecundity spawning, and select the corresponding period of low temperature period (slow development of each stage of the worm), when the number of eggs and young larvae from more to less, the top of tender shoots 4 to 5 tender Leaf larvae harmless, immediately erased by the victim, unified put shoot.
